move — move, translate, a graphic entity and its children.
move(h,xy) move(h,xy,"alone")
a handle, the handle of the entity to move.
an array [dx,dy] which gives the translation
vector to apply.
string keyword (optional).
This routine can be used to apply a translation to a graphics entity. If the entity has children, they will be also translated.
Given the keyword "alone" , only the specified entity needs to be redraw.
It must specially be used with the pixel_drawing_mode
property of the figure entity (see draw objects under
"xor" drawing mode).
